Ok, but sorry, what is so special about Javascript here ? Did this for good old Java services a few hundred times. With hot-fix on same or next day. Remote debugging is supported for a large number of languages. It is not unique to JS alone. JVMs support live visual profiling too - many engineers identify production performance issues this way. I don't think node js has anything to compete out of the box with the same level of convenience. (Last I checked, the profiling was bare bones primitive)
